General Information
CAEN RFID easy2log©RT0005 is a low cost, semi-passive UHF logger tag that allows to monitor temperature sensitive
products like perishable foods and pharmaceuticals, during transportation and storage. The combination of the high
resolution sensor, the large memory size and the standard RFID interface permits to realize effective track and trace
solutions for the cold-chain.
The RT0005 can be used with standard UHF RFID readers available on the market without requiring any additional
equipment thanks to its compatibility with the EPCGlobal C1G2 and ISO18000-6C standards.
The tag can be configured to store temperature samples in intervals from 1 second to 18 hours in the internal memory
that can contain up to 3,958 samples. The user can define up to 16 temperature ranges with independent threshold
alarms for a very accurate control of the temperature excursions. The tag can be started either using a button or via
standard RFID commands.
The tag is also able to calculate the Mean Kinetic Temperature and user configurable remaining shelf life time as well
as generate alarms in case these parameters exceeded user defined thresholds.
The RT0005 RFID logger can be used for multiple shipments thanks to the long battery life and the reset function thus
allowing to reduce the total cost of the solution and anticipate the ROI.

Operating states
easy2log©RT0005 tag behaves according to the following operating states:
Stand-by. Stand-by is the starting state of the tag. In this state the tag respond to reader interrogations, the log
memory is empty and the internal clock is not started. This is the lower power consumption state.
Idle. The tag is in Idle state when the internal clock is running, the memory is empty and the tag is waiting for a start
logging command. The start command can be issued either by an RFID command or by the button.
Active. The tag enters in Active state after having received the start logging command, in this state the tag wakes up at
defined intervals in order to acquire temperature samples and, eventually, it stores those samples inside the log
memory.
Sleep. The tag enters in the Sleep state at the end of a logging activity. Differently from the Idle state, in Sleep state the
tag's log memory is not empty and it is retained until a reset command is issued.

Manual interface behaviour
The easy2log©RT0005 tag has a simple manual interface that includes a button, a green LED and a red LED that,
depending on the configuration, permits to check the status of the alarms and to start/stop the logging activity. By
default, the button can be used only to check the status of the tag but not to start/stop the logging activity. Start/stop
function can be activated setting the Button Enable (BE) bit in the CONTROL register.
The manual interface behaves as follows:
Pressing the button quickly (less than 2 second) activates the check status function:
If the battery level is still sufficient for the logging activity and no alarms are active the green LED will stay lit for 2
seconds.
If the battery level is still enough for the logging activity but there are active alarms the red LED will stay lit for 2
seconds. The alarms causing the red LED to ligth are:
Memory full (see MEMFULL bit in STATUS register description).
ETA alarm (see ETA_ALRM bit in the STATUS register description).
Bin counters alarm (see BIN_ALMR bit in STATUS register description).
Mean Kinetic alarm (see MKT_ALRM bit in the STATUS register description).
Shelf life alarm (see SHL_ALRM bit in the STATUS register description).
If the battery has not enough charge to continue the logging activity the red or green LED will blink for 2 seconds (the
green one in the case of no alarms, red in case of some alarms).

If the BE bit is 1 (Start/stop function activated), in addition to the behaviour previously described, the manual interface
has the following features:
The start of the logging activity can be performed in the following way:
Hold down the button
Wait until the green LED lit and the red LED start blinking
Release and press again the button within 5 seconds to confirm the command otherwise the
command is ignored.
If the command is accepted the green LED will be lit for 15 seconds.
The acquisition is started.
And, if the SD bit is 0, also the following operation is allowed:
The stop of the logging activity can be performed in the following way:
Hold down the button
Wait until the red LED lit and the green LED start blinking
Release and press again the button within 5 seconds to confirm the command otherwise the
command is ignored.
If the command is accepted the red LED will be lit for 15 seconds.
The acquisition is stopped.

Histogram functionality description
The easy2log©RT0005 tag allows to define up to 16 different histograms bins. The user is able to decide the upper and
lower temperature limits for each bin: the lower limit of each bin is equal to the upper limit of the previous bin while
the upper limit can defined by the user (BIN_HLIMIT_[X] where is X is the index of the histogram bin). The first bin
starts always from the lower temperature limit of the tag while the upper limit of the last bin is always the higher
temperature limit of the tag.
Each histogram bin has a bit that allows to enable/disable the counter for the bin (BIN_ENABLE register). If the bin is
enabled, the corresponding counter (BIN_COUNTER[X]) is incremented when the sampled temperature value is greater
to the lower limit and less or equal than the higher limit. If the bin is not enabled the temperature values in the interval
defined by the corresponding bin are not counted.
For each bin it is possible to define a threshold value (BIN_THRESHOLD_[X]) in order to generate an alarm when the
counter is greater or equal to the threshold value. The generation of the alarm can be disabled setting the threshold to
0xFFFF (default value).
It is also possible to define a different sampling interval for each different bin in order to permit a fine grained sampling
in critical temperature ranges and a more relaxed sampling in standard temperature conditions. The sampling interval
time is modified after the detection of the first temperature sample value in a new bin (if the value of the temperature
falls in the same bin the sampling time dos not change, if it falls in a new bin the sampling time is updated with the
value of the BIN_SAMPLETIME[X] register where X is the index of the new bin).
Histogram bins configuration can be used also to control the storage of the samples inside the logging memory: for
each bin (if enabled) the user can choose to store or not in the memory the temperature value (depending on the state
of the corresponding bit in the BIN_ENA_SAMPLE_STORE register) and the time stamp (depending on the state of the
corresponding bit in the BIN_ENA_TIME_STORE). Disabling the sample storage for accepted temperature ranges can
provide a better handling of long term deliveries due to the memory saving. In this case it is necessary to enable the
storage of absolute timestamps together with the samples out of the acceptance range in order to keep track of the
chronological sequence. At the same time, the bin counter can be enabled also for the accepted temperature range in
order to have a feedback on the temperature trend for the entire delivery. Due to the availability of a large number of
bins, the accepted range can be divided in more than one bin in order to have finer grained information on the
temperature trend.
Examples of usage:
Let suppose that the user wants to monitor the temperature trend for frozen food, we can define some histogram bins
as follows:

Tab. 2.2: Example of histogram bins for frozen food
With this configuration the tag generates an alarm if the temperature was between -15°C and -10°C for a minimum
amount of time ranging from 20 min. to 34 min. and 59 sec. or if it was between -10 °C and 0 °C for a minimum amount
of time ranging from 5 min. to 14 min. and 59 sec. or greater than 0 °C just for a minimum amount of ranging from 1

Mean Kinetic Temperature calculation
The Mean Kinetic Temperature (MKT) is a simplified way of expressing the overall effect of temperature fluctuations
during storage or transit of perishable goods. MKT is useful in order to monitor the status of perishable items during a
shipment. The RT0005 tag is able to update the MKT every time it samples a new temperature. The MKT function can
be enabled or disabled toggling the state of the MKTE flag in the CONTROL register.
MKT is calculated using the following formula:
neee
R
H
MKT
n
RTH
RTH
RT
H...
ln 21
(1)
where ΔH is the MKT activation energy constant expressed in J/mol, R is the universal gas constant, n is the number of
samples and Tn is the temperature of the different samples expressed in °K.
The user can set a threshold value for the MKT; if the MKT exceeds the threshold, the tag generates an alarm setting to
1 the MKT_ALARM bit in the STATUS register.
The current MKT value can be obtained reading the MKT_VAL register while the threshold can be set writing the
desired value in the MKT_THRESHOLD register.
Remaining Shelf Life calculation
Shelf Life is the length of time that perishable items are given before they are considered unsuitable for sale or
consumption. For many products the spoilage rate increase of a perishable good is an exponential function of
temperature.
As well as the Mean Kinetic Temperature, the remaining Shelf Life calculation is useful in order to monitor the status of
an item during the shipment. The RT0005 tag is able to calculate the remaining Shelf Life using a linear approximation
of the Arrhenius algorithm every time it samples a new temperature. The remaining Shelf Life calculation can be
enabled or disabled toggling the state of the ARRE flag in the CONTROL register.
The remaining Shelf Life is expressed in hours and is calculated with the following formula:
nn
TT
refn tQSHLSHL refn
10
10
(2)
where SHLref is the Shelf Life reference expressed in hours, Tn is the temperature of the different samples expressed in
°C, Tref is the reference temperature expressed in °C, Q10 (unit less number) is defined as the ratio of the reaction rate
constants at temperatures differing by 10 °C from the reference temperature and tnis the sampling interval expressed
in hours for the selected bin.
The user can set a threshold value for the remaining Shelf Life; if the remaining Shelf Life is lower than the threshold,
the tag generates an alarm setting to 1 the SHL_ALARM bit in the STATUS register.The remaining Shelf Life value can be
obtained reading the SHL_TIME register while the threshold can be set writing the desired value in the
SHL_THRESHOLD register.
The remaining Shelf Life value can be obtained reading the SHL_TIME register while the threshold can be set writing
the desired value in the SHL_THRESHOLD register.
Battery measurement and behaviour
The RT0005 tag includes a battery measurement circuitry that allows to control the battery charge level.
Four battery charge levels are defined: Full (3), Normal (2), Low (1), Empty (0); values can be obtained reading the
BAT_LSBIT and BAT_MSBIT in the STATUS register. The RT0005 tag behave normally when the battery is at the Full or
Normal battery level, while it is automatically put in Sleep state when the level reach the Low value.
When the battery level status is Low (1) or Empty (0) the battery level is considered critical so the condition is reported
by the manual interface as described in the relevant paragraph.
